If the slope is -1, this means that for every time you add 1 to X, you add -1 to (subtract one from) Y. So, the line would go down at an equal amount as it goes over. If the line crosses 0,0 then it would appear to cut the upper left and lower right quadrants in perfect triangular halves.
Its exact appearance will depend on the scale used for the axes. If the scales are the same then the graph will be a straight line, going up from left to right, at an angle of 45 degrees.
It is a horizontal line that intersects the y axis at negative 1

Solve the line equation for "y", to get it in slope-intercept form. You can immediately read the slope from this equation.Divide -1 by (slope of this first line) to get the slope of the second line - the one perpendicular to the given line. Write an equation for any line with this slope.

It is a horizontal line that intersects the y axis at negative 1
The slope is zero.
Any graph with the slope of -1/2
It looks like a straight line, that crosses the y-axis at y=1, and slopes up from left to right with a slope of 1/2 .
The slope of the graph of [ y = x + any number ] is 1 .
The equation has no slope. The graph of the equation is a straight line with a slope of -1 .

If you had a problem like this... y=3x-1 you would go down 1 point on the graph and point it then go up three and over one as the slope.
It is 6 and the y intercept is -1
The slope of the graph of that equation is -1.
1) You write the equation in slope-intercept form, if it isn't in that form already. 2) An easy way to graph it is to start with the y-intercept. For example, if the intercept is +5, you graph the point (0, 5). Then you add an additional point, according to the slope. For example, if the slope is 1/2, you go 2 units to the right, and one up, and graph a point there.
